I am not 100% sure, I either have a bad alternator or bad battery ... my Commander is a 2006 so the battery is probably due.
It was cranking over really slow lately and I had to boost it a couple times (luckily I was home both times) I installed an on board battery charger (I'll post more on that and some pics another day) and plugged it in overnight every night for the last 2 weeks and this morning it would not start.
So I have a brand new battery here, but did't know if it would fit, so I installed the battery and put two big pieces of PlayDoh on the terminals ...
... and gingerly closed the hood ...
As you can see the PlayDoh hardly squished down at all, IT FITS!
I had to bend the positive connector a bit so it would reach without putting stress on the wire and I reversed the bolt on the negative side so the vent covers would come off easy for checking the water level etc.
All in all a nice fit especially considering the battery was free
the battery has significantly MORE cranking amps but a little less reserve capacity.
Hopefully that was the problem I put the original battery inside on charge and will have it tested this week.
Oh and yes I tossed the PlayDoh out
no sence letting the kids play with it after that
